The Big Spin
Does the ball really curve?
We have looked at the principles of motion. In this lesson we make
connections with a thrown or kicked ball.
The question is does a ball curve or is it an optical illusion?
At the end of the lesson you will write a reaction essay covering the principle
that relate to a thrown ball.
Batters insist that a good pitcher is able to throw a "filthy" breaking ball
that curves drasticly.
There are several hypotheses that could explain batter statements:
A ball curves. It is not an optical illusion.
The ball drops because of gravity
The seams of the ball influence/create the altered flight of the ball.
There physical imperfections in the ball that affect the flight of a thrown,
batted, or kicked ball.

Try out a curve ball
Can a pitcher throw a ball so hard that it rises? Would your hypothisis
change if we were to throw a softball with a fastpitch softball motion?
What affect does atmoshpere have on a thrown ball?
Does the ball react differently in Cleveland or Denver?
What about a ball thrown in the Himalyas?
